Abstract (en)
Apparatus for washing hydraulic circuits involved in the preparation of milk-based beverages in machines (1) for automatically dispensing hot drinks and/or in machines for preparing and supplying espresso coffee, said circuits comprising at least one first hydraulic path (6) which extends between a point (8a) for detachable connection to a milk storage vessel (8) and the orifice of at least one pouring spout (4, 4a) of a delivery device (2). A motor-driven pump (11) is arranged along said first hydraulic path (6), and valve means (12) allow washing liquid, drawn from a source (13), to reach said first hydraulic path. The apparatus envisages a hollow cartridge (22) provided with unions which, when it is required to perform washing, allow connection of the orifice of said at least one pouring spout (4, 4a) supplied by said first hydraulic path (6) to the said connection point (8a) which can be detached from the milk source (8). The washing liquid is circulated by the motor-driven pump (11) along the closed hydraulic path (6) passing through the cartridge (22) which may contain a detergent and/or disinfecting substance and inside the pipes of the delivery device (2) which does not need to be disassembled.
